Dear Collaborators,
Solar activity has continued at moderate levels since the last message, although NOAA 13521 has remained quiescent. NOAA 13519 near the southwest limb was the source of an M4.2 flare at 05:19 UT today and shall be the new target region. The region has undergone significant flux emergence ahead of its leader spot and appears to have a complex magnetic configuration. Further C-class flares likely with chance of an additional low M-flare before west limb passage.
The position of NOAA 13519 on 21-Dec-2023 at 12:30 UT is:
S11W65, ( 868", -174" )
See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
